LAC-China merchandise trade was almost perfectly stable in 2020. This is noteworthy in itself, as LAC GDP fell more than 7 percent in 2020 according to IMF estimates, losing growth of a decade. , and regional merchandise exports fell overall (United Nations 2021). However, due to stable trade with China amid such a steep economic downturn, LAC merchandise trade flows with China grew to record levels of regional GDP.
LAC merchandise exports to China increased slightly from $ 135.2 billion to an estimated $ 135.6 billion, and China’s merchandise exports to LAC fell slightly from $ 161.3 billion to an estimated $ 135.6 billion. $ 160.0 billion. But as LAC’s regional GDP fell dramatically, both imports and exports increased significantly as a percentage of GDP, and the balance grew slightly, from 0.5% to 0.6% of regional GDP.
Trade is likely to see the effect of continued volatility in metal prices as the world economy recovers and the effect of China’s stimulus on construction recedes. Although metal prices rose in 2020, The Economist Intelligence Unit and the World Bank expect the price of iron to fall again in the coming years, while the outlook for copper is somewhat more optimistic. This is good news for exports of mining machinery products from China to Latin America, especially drilling equipment. Our company Hebei Gimarpal Machinery Technology Co., Ltd. is specialized in manufacturing and exporting mining drilling tools with own factory, such as taper bar, threaded bar, chisel bit, button bit. Therefore, 2021 will be a new opportunity.
A progressive cavity type volumetric hole bottom power machine, referred to as screw drill. The screw drill, which uses mud and clean water as the power medium, is transported to the bottom of the hole through the center hole of the drill rod, and is essentially an energy conversion device that converts the pressure energy of the liquid into mechanical energy. During drilling, the screw drill directly drives the core tube and the drill bit connected to the drive shaft at the bottom of the hole to rotate. The entire drill string is only used as a channel for conveying high-pressure working medium and a rod supporting the counter torque of the drill bit, and does not rotate. Compared with conventional drilling, screw drilling has many advantages, such as drastically reduced drill rod wear and high drilling speed. It is the main tool for drilling directional holes and has played a role in the field of drilling.
In 1955, the United States Christensen Mine Drilling Products Company began research based on the Moinuo principle, and it was the first to succeed in 1964, named “Dana Drill”; the Soviet Union successfully studied the “convex” screw drill in the early 1970s; China The Exploration Technology Research Institute of the Ministry of Mines successfully developed screw drills in the early 1980s. The countries that have produced screw drills so far include the United States, Russia, China, and Germany.
